Unbleached, but mainly due to growing up with it. There is definitely a difference in taste. It’s also, at least here in Germany, available at practically any store, whereas bleached filters are only available at bigger stores.

I tend to get whatever is available, but always rinse the filter before using it anyway, and haven’t noticed any difference between the two.

I always recommend bleached. Just getting started, you might not notice but the unbleached ones tend to add a bit more of a papery taste.

Prefer bleached but if you give it a good rinse it makes no real difference in my experience.

Both are fine, for most any good coffee, you’ll have an equally good time if you give the unbleached filter a pre-rinse with hot water. But if you’re venturing into Very Expensive Fancy Coffee (like $30 > per 100g), unbleached is probably the way to go to not have to worry about the flavour mixing.

Filters did not come to mind when I saw this title and was very concerned as I clicked through.

I prefer unbleached, but I also don’t end up doing a pre rinse of the filter. To me what’s made the most difference is the grind of the bean and the temp of the water. You’ll just have to find what’s right for the flavor you like. That’s the beauty of pour over!

The best thing you can do is test this for yourself.

Steep a plain coffee filter in water, taste it, and determine your findings from there. Repeat with each filter candidate
